Spurious measurements with a Hokuyo 2D LIDAR [closed]
Hi all,
I am experiencing a serious issue with a Hokuyo UST-20LX LIDAR sensor that I can't seem to shake and I was wondering if anyone has had any experience with it or any intuition.
As you can see in the following image sequence the sensor reports some measurements extremely close to the actual device but in reality the sensor is far away from obstacles:
What is more is that, when I place the robot in one rectangular surrounding (a standard desk open at one end only basically) and let the range measurements accumulate, the sensor exhibits the same false measurements near its maximum angle (forming a perfect line!) and, additionally, really distorted surroundings starting around -10 degrees and onward, and around the minimum and maximum angle. The desk's walls are straight as an arrow and they only form a Π shape. The measurements after the left-hand side wall do not correspond to obstacles.
I launch the sensor with the urg_node wrapper which gives me little to work with. I'm working on kinetic.
Does anyone have any past experience with this? Or is the sensor toast?
